Testosterone is a sex steroid hormone found in both men and women, although higher levels in men. Levels in both men and women decline from middle age. Informing yourself of your testosterone level can help you to understand if your value is as expected, low or high for your age and biological sex. Your result can then be considered in the context of any symptoms you are experiencing, and tailored advice given to address any issues identified. This might include resistance type exercise to support testosterone levels, and/or reviewing dietary intake matches demands from exercise training and/or if sufficient recovery being taken.
Our home testosterone test measures total testosterone which is a combination of free and bound testosterone. Testosterone is an essential male hormone integral to multiple functions in the body including energy, bone health, mood, libido and muscle growth. Our convenient testosterone test kit will identify if your levels require improvement.
Testosterone in men is an important sex hormone which regulates libido (sex drive), body mass, strength as well as being involved in the production of red blood cells and sperm.
As men get older, the amount of testosterone they produce falls. Some of the testosterone in men is converted to another hormone called oestrogen (specifically oestradiol). Oestradiol helps with libido and erectile function and so, as testosterone levels drop, so too does the level of oestradiol.
It’s not just age though that can reduce testosterone production. Overtraining and/or under fuelling in exercise can also result in low testosterone levels.
Several symptoms can arise from low testosterone in men including low mood, fatigue, difficulty sleeping, low libido, difficulty gaining muscle mass and predisposition to gain fat. Low testosterone is also associated with an increased risk of injuries such as stress fractures which may have significant consequences in older men but can also impact upon your usual daily routine including exercise and training.
A high testosterone blood test result can affect fertility by causing a low sperm count. A high intake of steroids to aid sports performance can also stop the body producing testosterone.
Our testosterone test isn’t just for men. Women also produce testosterone in smaller amounts and it is involved in female sex drive and the health of the bones, breasts, vagina, and menstruation.
Low levels of testosterone in women can cause missed or irregular periods, osteoporosis, decreased libido, vaginal dryness, and infertility.
High levels of testosterone in women can indicate can be caused by Polycystic Ovary Syndrome (PCOS).
Some exercises initially increase testosterone levels but this is usually only for a brief period. However, there is a fine balance needed for healthy testosterone levels. For example, intense training without adequate rest and recovery can cause a significant reduction in testosterone levels and overtraining syndrome.
You may be at risk of overtraining syndrome if your are experiencing symptoms such as fatigue, low motivation, depression and a slow heart rate.
Testosterone has vital roles in muscle mass and strength as well as being vital for maintaining bone density. So, low testosterone can increase the risk of fractures which will negatively impact your training.
Because of the hormone’s role in muscle mass, if testosterone levels are too low, your body may start to break your muscles down to extract energy. Ultimately, this will affect your overall performance.

Testosterone is a male sex hormone also known as an androgen. It has a vital role in the sexual development of men, particularly sperm production as well as regulating bone and muscle mass.
It’s also an important hormone in women and is responsible for regulating their sex drive too as well as regulating bone and breast health amongst other things.
Testosterone levels are controlled by the brain and pituitary gland and once it has been made, it is transported by the blood to the various parts of the body which require it to function.
Our testosterone blood test measures your total testosterone level and it’s really simple to do.
Once you have purchased your test online it will arrive in a box that easily fits through your letterbox. The kit contains everything you need to carry out your finger-prick blood test at home, complete with detailed instructions. Once you have collected the sample for your testosterone test, simply put it in the pre-paid envelope and post back to us. The tests are carried out by our accredited labs and reviewed by a GP or nurse. Your results will be available on your Forth dashboard within 2 working days of receipt.
Some men are genetically predisposed to increased testosterone. An increased testosterone count in men can be caused by adrenal or testicular tumours. Even harmless tumours, known as benign, can increase testosterone levels. Signs of high testosterone in men include:
Taking too much testosterone replacement therapy can also result in a high level and may be accompanied by some of the unpleasant side effects. Increased testosterone also raises cholesterol levels which can put men at greater risk of heart attacks and stroke.
PCOS affects the function of the ovaries in women. It is a common condition where there is an increased production of follicles and testosterone. Within these follicles, eggs develop but are not released. That means ovulation doesn’t occur and can make it difficult to conceive.
Approximately one fifth of women in the UK have PCOS and almost half experience no symptoms.
Two types of testosterone can be tested, free and total.
Most testosterone molecules bind with sex hormone-binding globulin (SHBG) or albumin. This is known as bound testosterone.
Free testosterone, however, isn’t attached to any other molecules in the blood and so is readily available for use by the body. Total testosterone measures the combined amount of free and bound testosterone. So, your total testosterone level will always be greater than your free level.
The normal testosterone level for men is between 8.65 nmol/L and 29 nmol/L.
Exercise initially increases testosterone levels when you workout but the effects may not be long-term.
There are specific types of exercise which can help to support the production of testosterone, particularly strength and resistance-based exercises.
TRT should only on the advice and guidance of a medical doctor. For those competing in sport, testosterone is on WADA banned list.
Taking part in strength and resistant type exercise can help with the production of testosterone. Other factors which can support testosterone levels are getting good quality sleep, eating a healthy balanced diet, losing weight if you’re overweight and reducing stress.
You will need a diagnosis from a registered medical professional, but a high testosterone level can be an indicator of PCOS. You may also experience symptoms like excessive hair growth, irregular periods, weight gain and difficulty conceiving. The condition also increases the risk of type 2 diabetes.
